The other area I feel can really help is grouping in the regular classroom. (Don't know if you have any control over this, but it has been our biggest obstacle in our school.) Our school until recently had a policy of dividing up all the gifties, spreading them evenly throughout all the regular classrooms. If there was a near peer in my daughter's class, it was by sheer accident (there rarely was one.) This year, both my kids are in classes where there are 3-4 kids who are more similar to them in terms of ability. (Can't tell yet if it is a true policy change or just accidental, but it is a big difference from previous years.) It has made a world of difference- suddenly both kids have a crowd of friends and are much more "socially successful" if you want to call it that.
